volvulus

Twisting of a loop of intestine. Volvulus causes obstruction to the flow of contents and threatens occlusion of the supplying blood vessels. This will inevitably lead to GANGRENE of the affected segment of bowel unless quickly relieved by surgery. This may involve removing the affected loop of bowel and joining up the free ends.
